Comparison of 1 and 2 days per week of strength training in children

The purpose of this study was to compare the effects of 1 and 2 days per week of strength training on upper body strength, lower body strength, and motor performance ability in children. Twenty-one girls and 34 boys between the ages of 7.1 and 12.3 years volunteered to participate in this study. Participants strength trained either once per week (n = 22) or twice per week (n = 20) for 8 weeks at a community-based youth fitness center. Each training session consisted of a single set of 10-15 repetitions on 12 exercises using child-size weight machines. Thirteen children who did not strength train served as age-matched controls. One repetition maximum (1RM) strength on the chest press and leg press, handgrip strength, long jump, vertical jump, and flexibility were assessed at baseline and posttraining. Only participants who strength trained twice per week made significantly greater gains in 1RM chest press strength, compared to the control group (11.5 and 4.4% respectively, p < .05). Participants who trained once and twice per week made gains in 1RM leg press strength (14.2 and 24.7%, respectively) that were significantly greater than control group gains (2.4%). On average, participants who strength trained once per week achieved 67% of the 1RM strength gains. No significant differences between groups were observed on other outcome measures. These findings support the concept that muscular strength can be improved during the childhood years and favor a training frequency of twice per week for children participating in an introductory strength training program.     

Connecting Classrooms in Pre-service Education: Conversations for learning

Many students enter pre-service education programmes believing that their practical learning experiences will occur in schools and that their theoretical learning experiences will occur in the university or college setting. Research shows that frequently student teachers retain this perception throughout their programmes without acknowledging the interplay of theory and practice in their learning. Through the use of communication technologies, student teachers participating in the Bachelor of Teaching degree at the University of Otago are encouraged to make connections between the activities in their university-based classes and those of classrooms in primary schools. Frequent dialogue through fax, audio-conference and e-mail between student teachers based in the university and children and their teachers in classrooms enables them to access the thinking of children and teachers, and provides additional opportunities to theorise their practice and practise their theory. Student teachers are provided with a range of opportunities to explore the potential of information technologies in education while interacting with children and teachers beyond the traditional practicum experience. The use of technology to connect student teachers to learners in classrooms challenges the conventional teacher education curriculum.     

You Need More Organization Bro: Relationship Building in Secondary Writing and Revision

In this article, we describe the peer-response workshop we conducted in an ethnically and linguistically diverse secondary school classroom in an urban center in the southwest. We show how the three main parts of the workshop combine to help students cultivate writing relationships in which they see writing as social and co-constructed, rather than as a solitary act performed for the teacher.     

Managing the delicate matter of advice giving: accomplishing communicative space in Critical Participatory Action Research

ABSTRACT

Critical Participatory Action Research (CPAR) requires communicative space to develop shared understandings and decisions. We examine the interactional accomplishment of such a space between a classroom practitioner and an academic researcher when meeting to reflect on a lesson and agree on future action to bring about change in the practitioner’s classroom practice. Conversation analysis of an audio recording of the meeting establishes how advice giving emerged and was managed as a delicate matter that required achieving shared understandings of what actually happened in the lesson, what could have happened, and what should happen in future lessons. Findings provide insights into how participants used reported and hypothetical speech to manage advice and reach agreement, produce and maintain intersubjectivity through interaction, and address epistemic asymmetry related to the differing experiences and roles that they brought to the action research study. Overall, the article contributes understandings of the ways that interactions produce communicative space in CPAR.     

Pulmonary monoclonal antibody delivery via a portable microfluidic nebulization platform

Nebulizers have considerable advantages over conventional inhalers for pulmonary drug administration, particularly because they do not require coordinated breath actuation to generate and deliver the aerosols. Nevertheless, besides being less amenable to miniaturization and hence portability, some nebulizers are prone to denature macromolecular drugs due to the large forces generated during aerosolization. Here, we demonstrate a novel portable acoustomicrofluidic device capable of nebulizing epidermal growth factor receptor (EGFR) monoclonal antibodies into a fine aerosol mist with a mass median aerodynamic diameter of approximately 1.1 μm, optimal for deep lung deposition via inhalation. The nebulized monoclonal antibodies were tested for their stability, immunoactivity, and pharmacological properties, which confirmed that nebulization did not cause significant degradation of the antibody. In particular, flow cytometry demonstrated that the antigen binding capability of the antibody is retained and able to reduce phosphorylation in cells overexpressing the EGFR, indicating that the aerosols generated by the device were loaded with stable and active monoclonal antibodies. The delivery of antibodies via inhalation, particularly for the treatment of lung cancer, is thus expected to enhance the efficacy of this protein therapeutic by increasing the local concentration where they are needed.     

The Impact of a Pedagogy of Teacher Education Seminar on Educator and Future Teacher Educator Identities

Educators require support as they move from classroom to higher education settings. This collaborative self-study provides insight into one such support space, a doctoral seminar titled Pedagogy of Teacher Education, and how our identities as educators and future teacher educators developed through participation in the course. Several important themes emerged as we negotiated and adopted new identities as educators, and future teacher educators and researchers. These themes include our development of a collaborative mindset, a teacher educator-researcher perspective, and a critical self-awareness. The findings draw on our professional and personal histories to explore the prominent features that influenced and shaped our identities as educators and future teacher educator-researchers. In sharing our development as educators and future teacher educators, this article provides insights into the ways in which doctoral students in education begin to develop their identities and pedagogies through guided support from more experienced teacher educators.
